The video tutorial explains how to subtract polynomials using two methods: the vertical method and the distributive property method. The vertical method involves aligning polynomials vertically and subtracting them, while the distributive property method involves converting subtraction into addition by distributing the negative sign. Both methods ultimately lead to the same result, demonstrating their effectiveness in solving polynomial subtraction problems.

What are the two methods introduced for subtracting polynomials?

• Vertical and Distributive Property

• Vertical and Horizontal

• Addition and Subtraction

• Horizontal and Distributive Property
